As cap 4 overlies the blade as shown in Fig. 2, the handle is moved upwardly against the action of the spring and is then rotated so that the upper end of the handle is screwed onto the stud of the cap. In this way the cap is brought to bear on the blade and clamp the blade between the capand plate.

As the blade is clamped, the rim 54 of the cap bears thereon adjacent the cutting edges of the blade and in fact quite closely to the said edges and inlthat way holds the cutting edges firmly on to the ridgeslat the marginal edges of the plate.

The modification of the blade shown in Figs. 4, 5, 6 and'7 will now be explained.

shown inFiga 1, so as to provide a central opening 72 and radial slots 74 for receiving the bossandbars of the cap. Theends of the slot are extended to a point quite close to the corners of the blade so that the sides of the blade indicated at 76 may move relative to one anotherand be pressed onto the plate by the cap inthe desire-d manner.

The blade 80 in Fig. 5is similar to the blade shown in Fig. 4. In this case the ends 83 of slots 82 therein are formed to give the utmost flexibility of the blade at the corners marked 84.

The blade shown in Fig. 6, indicated as 90, has a central opening 92 and slots 94 radiatingtherefrom towards the corners of the blade. As in the other cases the slots terminate closely adjacent the corners to provide the utmost flexibility of the blade.

The blade shown in Fig. 7 has a central opening 102 and slots 104 which are formed with restricted openings. 106 adjacent the central opening. This is so the bars of the cap may. be embraced closely adjacent the hub portion thereof.

The blade 110 shown in Fig. 8 has acentral opening 112 with slots 114 radiating therefrom, as shown. This opening and the slots are to receive the parts 50 and 52 of the cap and by the means thereof is held between the cap and plate against relative movements; 1

In this form of the invention a plate 115 is provided with alternate grooves and ridges 117 and 119 on opposite sides thereof. A sleeve 121 is carried by the lower end of the plate and slidably receives an upper shank portion 1250f a handle 123. As in the former case this handle 123 is provided with a threaded socket127 in its upper end for receiving a stud 129 of a cap 137. -A spring 131 is interposed between the upper end of the handle and the under side of the plate 115 as in the former case;

Bar members 133 are provided on the upper side of the plate and'are receivable in slots 135 of the eap137. The cap pro- 123 to engage the'st'ud the cap may be caused to firmly clamp the blade to the plate.

- -The cap 137 is out out at to expose portions of the upper side of the blade and provide bars 147 at opposite sides thereof for A blade 7 0, as in Fig. 4 has a cut-out which is centrally disposed similar to the blade bearing onthe blade. In this waythe cutting edges of the blade are held firmly against the serrated edges of the plate.

In Figs .11, 12 and 13 there is shown three forms of. blades which will fit the plate and cap'described.

The blade 151 shown in Fig. 11 has a central opening 153 for receiving the stud 129 of the cap and diverging openings 155 at opposite sides thereof for receiving the parts 133 of the plate. 1

The blade 161 in Fig.- 12 has an opening which diverges from a narrow central portion 163 to relatively wider outer portions 165. This opening is arranged to receive the parts 133 of the plate and the stud-129 and in" co-operation with the parts 133 the blade is held against relative shifting movements when clamped between the cap and plate. v I I The blade 171 in Fig, 13 has an enlarged central. opening 173 and tapering openings 175 at opposite ends thereof for receiving the part 133 of the'blade, so that it will be held against relative movements when clamped between the plate and cap.

Any of these formsofblades are adapted for clamping between the plate and clamp and are so shaped as to co-operate with the parts ofthe blade and cap whereby they are held against shifting movements while so clamped.

This invention may take various forms without departing from the spirit and scope thereof and it is desired to be limited, if at all, by the appended'claims rather than by the foregoing description;

What is claimed is: 1

'1. A razor of the'class described comprising-in combination, a blade supporting plate provided with'an opening a tubular member depending from said plate around the opening, a handle having its upper part reciprocable and rotatable in said tubular member, the lower end of the tubular member having a restricted opening, the upper end of the handle being enlarged to prevent separation of the plate from the handle, a cap hinged to said plate for clamping a blade thereoma threaded-stud carried by the cap for disposition through the opening in the plate, a threaded socket provided in the up per end of the handle for receiving the stud, and an expansible spring in said tubular member between the plate and the enlarged upper end of the handle.

2. A razor of the class described comprising in combination, a blade supporting plate having a central opening therethrough, a

sleeve depending from said plate around the opening and having a restricted opening at its lower end, a cap hinged to said plate and having openings adjacent the marginal edges thereof to provide relatively narrow rims along its side edges for overlying the side edges of a blade positioned between the plate and the cap, said cap and plate being provided with interfitting raised portions and grooves, a handle having its upper part reoiprocable and rotatable in said sleeve, aflange on the upper end of the handle, cooperating with the lower end portion of the sleeve to prevent disengagement of the handle from the sleeve, a threaded stud depending from the cap for disposition through theopening in the plate and extending into the sleeve, a threaded socket in the upper end of the handle for receiving the threaded stud and an expansible spring arranged in the sleeve between the plate and the flange on the handle.

In testimony whereof I affix my signature.
